Mapping scoping reviews in neurosurgery: a scoping review protocol

The realm of neurosurgery is currently witnessing a surge in primary research, underscoring the importance of adopting evidence-based approaches. Scoping reviews, as a type of evidence synthesis, offer a broad perspective and have become increasingly vital for managing the ever-expanding body of research in swiftly evolving fields. Recent research has indicated a rising prevalence of scoping reviews in healthcare literature. In this context, the concept of a 'review of scoping reviews' has emerged as a means to offer a higher level synthesis of insights. However, the field of neurosurgery appears to lack a comprehensive integration of scoping reviews. Therefore, the objective of this scoping review is to identify and evaluate the extent of scoping reviews within neurosurgery, pinpointing research gaps and methodological issues to enhance evidence-based practices in this dynamic discipline.

The method framework of Arksey and O'Malley will be used to conduct the scoping review. A thorough literature search will be performed on Medline, Scopus and Web of Science to find eligible studies using the keywords related to neurosurgery, scoping review and its variants. Two reviewers will independently revise all of the full-text articles, extract data and evaluate the study extent. A narrative overview of the findings from included studies will be given.

This review will involve secondary analysis of published literature, and therefore ethics approval is not required. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist will be used to guide translation of findings. Results will be disseminated through peer-reviewed journals and presented in conferences via abstract and presentation.
